METHOD AND PLANT FOR CONVERTING GRAINS

摘要

A method for converting grains (B), containing at least starch, bran (D), germ (G) and proteins (L), includes a washing (3), a grinding (2), a first (4) and second (5) hydrolysis through enzymes, a fermentation (6) through yeasts and a distillation (7) of grains (B) to obtain alcohol (E) and a liquid. The method (1) provides: to subject grains (B) to solid fraction separation (8), by separating bran (D) before the fermentation (6); to subject to fermentation (6) grains (B) deprived of bran (D); to subject to distillation (7) grains (B), deprived of bran (D) and fermented, so obtaining alcohol (E) and a aqueous liquid (F) nearly without solid residues.
